Welcome back to Rebel Dot’s ongoing series on Web 3.0. Check out our first post in this series right here. Today’s post will explore the implications of blockchain in cyber security. Cyber security is a growing issue, so let’s look at how this budding technology can help solve it. 

How you can use blockchain in cyber security 

Blockchain technology can revolutionize cyber security. And one of the key ways it does this is by being naturally resistant to cyber security attacks. It’s immutable, decentralized, and in many cases, publicly displayed. 

Combined, these features of blockchain make it very difficult to manipulate. And if manipulation does occur, it should (in theory) be very easy to spot. 

This makes it a secure alternative to many other types of technologies, and it’s one of the many reasons we anticipate that blockchain will play a pivotal role in Web 3.0. You can even increase the security of blockchain by implementing machine learning that is capable of detecting manipulation before it has a chance to take root. 

Blockchain applications in cyber security

Of course, the cyber security benefits of blockchain mean nothing if it doesn’t have real-world applications. With that in mind, here are a handful of real-world use cases for blockchain in cyber security. 

Blockchain IoT security

IoT devices and networks are poised to be a significant part of Web 3.0, expanding our idea of how a connected world looks. But a more connected world also means a more vulnerable one. 

That’s where blockchain can help. Blockchain technology can be used to verify the data collected by IoT devices and store it in a secure, tamper-proof way. This makes the data more reliable and less hackable — two major concerns in the IoT field. 

Cryptocurrency wallet security

Blockchain is already widely used for cryptocurrency wallet security. Blockchain tech is perfectly suited to financial use cases, because that’s what it was designed for. It can secure transactions, reducing the high volume of fraud currently associated with cryptocurrency. As cryptocurrency becomes a more common medium of exchange, this kind of security will be essential. 

Security for medical records

One of the most innovative use cases for blockchain in cyber security is as a tool for securing medical records. Medical records are highly sensitive, difficult to transfer between healthcare providers, and vitally important. 

Similar to financial transactions, this is an area that blockchain is well-equipped to handle. You can share records between healthcare providers on a public or private blockchain, ensuring that all information is updated, available, and, importantly, unlikely to be corrupted.
